VESTIBULE-DIAPHBAGM IOR RAILWAY-CARS.

To all whom it may concern:

Be it known that I, EDWARDA. SGHREIBER, a citizen of the United States,residing at '.Chicago, in the county-of Cook and State of Illinois, haveinvented certain new and useful -Improvements in vestibule-Diaphragmsfor Railway-Cars, of which the following is a specification.

My invention relates to a vestibule dia'- phragm for railway cars, andhas for itsv principal object to provide a vestibule diaphragm which maybe made entirely of metal and which will be simpler and more economicalin construction and more durable than the leather diaphragm in use atthe present time, or the various substltutes for the same which havebeen heretofore pro-- posed and experimented with to a certain extent.

I ed as to resist the lateral displacement ofthe 30 A further object oftheinvention isto provide an all metal vestibule diaphragm which will belight in weight and extremely Aflexible fso as to accommodate itself tothel relative `changes of position of the cars between which it isplaced and, at the same time, will be water and dust proof.

The invention has for a further object to provide a vestibule diaphragmso constructface plates with respect to each other which tends to vtakeplace when the train rounds a curve; my invention', in this respect,providing a construction of the diaphragm whereby such movement orlateral chafing is either prevented or the face plates automent when thecurve has been passed. Be-

cause of this feature of the invention it is possible, in some cases, todo away with the v use of the springs frequently employed forkeeping thediaphragm face plates 1n prope position withA respect to eachother. jThe invention has for further objects such other new and improvedconstructions, ar-

rangements and devices relating to metal vestibules for railway cars aswill be hereinafter described and claimed.

The invention is illustrated, in a pre- -ferred embodiment, in theaccompanying drawings, in which- Figure 1 is a view, 1n perspective, ofa diaphragm constructed in accordance with my invention shown asarranged in the.

usual manner between the' end of the car and a face plate and adapted tobear against Specification of Letters Patent. y

By constructing thecollapsible elements ofthe diaphragm of sary by the relative changes ofposition as' between the ends of the car due to unevenness of the track,banking at curves, and other causes. A vestibule diaphragm must becapable of a certain. amount of lateral movement and also a certainamount of vertical movement in order that it may accommodate itself tothe oscillatory movements of the car to which it is attached withrespect to the adjacent car. rl`he structure above described has thiscapacity besides being light, strong, sightly in appearance, durable andwater and dust proof. Furthermore, as any lateral or vertical movementof the diaphragm face plate puts the structure under stress, with theresult that thesefehaing movements are minimized and the face plate isautomatically brought back to proper alinement with the engaging faceplate when the forces bringing about the displacements have ceased toact. For this reason it is possible, in many cases, to do away with thesprings which are frequently employed on passenger cars to return theface plates to their normal positions after displacement due to chafing.

While I have described my invention as embodied in a preferredconstruction, it will be understood that modifications might be made inthe design, construction and arrangement of the parts without departurefrom the principles of the invention. Therefore l do not wish to beunderstood as limiting the invention to the particular constructions,arrangements and devices shown eX- cept so far asthe claims explicitlycontain such limitations.

I claim:

1. A vestibule diaphragm for railway cars comprising a plurality ofhollow sheet metal elements having open sides and ar` rangedtelesco-pically' one within the other and formed with inturnedflanges-along said open sides which bear respectively upon oppositesides of the adjacent elements.

2. A vestibule diaphragm for railway cars comprising a. plurality ofhollow,

arched, sheet Vmetal elements having open `sides and arrangedtelescopically one within the other and formed with inturned flangesyalong said open sides which bear respectively upon opposite sides ofthevadjacent elements. y

3. A vestibule 'diaphragm for railway Cars comprising a plurality ofhollow ,sheet inmate metal elements having open sides and arrangedtelescopically one Within the other and formed with inturned flangesalong said open sides which bear respectively upon opposite sides of theadjacent elements, and an element consisting of a piece of sheet metalwhich extends into the narrowest of said hollow elements and is formedat its inner end with a guiding bead bearing against opposite sides ofsaid hollow element.

4. A vestibule diaphragm for railway cars comprising a plurality ofarched hollow sheet metal elements having open sides and arrangedtelescopically one within the other and formed with inturned flangesalong said open sides which bear respectively upon opposite sides of theadjacent elements, and an element consisting of a piece of sheet metalwhich extends into the narrowest of said hollow'elements and is formedat its inner end with a guiding bead bearing against opposite sides ofsaid hollow element. l

5. A vestibule diaphragm for railway cars colnprising a plurality ofelements having a Sliding engagement one with the other on linessubstantially longitudinal of the car and means on each element engagingopposite sides of the adjacent element for preventing said elementsfrombeing dis- 95 engaged one from another when the diaphragm is expanded.

6. A vestibule diaphragm for railway cars comprising a plurality ofhollow sheet metal elements having open sides and arranged tele- 100scopically one within the other, each element being narrower than theinternal width of the element into which it projects and being formedVwith a guiding member bearing against the opposite inner surface of theinelement being narrower than the internal 120 width of the element intowhich its projects and being formed with a guiding .member bearingagainst the inner surfaces of the inclosing element, -the inclosingelements torined,` in each case, with oblique flanges which bear uponthe sides of the elements `inclosed respectively.
